Suppose it is believed that the probability a patient will recover from a disease following medication is 0.7. In a group of fifty such patients, the number who recover would have mean and variance respectively given by (to one decimal place) Find the mean Find the Variance
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
